Marco was never in a Nazi concentration camp. And perhaps the rest of his past was fabricated, too, a combination of his delusions of grandeur and his compulsive lying. In this hypnotic narrative, which combines fiction and nonfiction, detective story and war story, biography and autobiography, Javier Cercas sets out to unravel Marco’s enigma. With both profound compassion and lacerating honesty, Cercas probes one man’s gigantic lie to explore the deepest, most flawed parts of our humanity.
